Recombinant Human CT38-11R Protein

Product Name: Recombinant Human CT38-11R Protein
Catalog #:  HRP-2003
Manufacture:  LD Biopharma, Inc.

Human CT38 (also named as ferritin heavy polypeptide-like 17 =FTHL17) gene encodes a ferritin heavy chain-like protein. This gene is primarily expressed in embryonic germ cells. CT38 protein may lack ferroxidase activity. Normally, this gene expression is restricted in human testis tissue, but also expressed in a wide variety of cancer tissues. As such, CT24.2 is a good candidate protein for anti-tumor vaccine development.

Full-length human CT38 cDNA (182aa) was constructed with codon optimization gene synthesis and expressed with a human Alpha Fetal Protein at N-terminal / His Tag /TEV enzyme site/ and 11 arginine (11R tag) at C-terminal. This protein was expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
